Mons Bradley
Mons Bradley is a lunar mountain massif in the Montes Apenninus range, along the eastern edge of the Mare Imbrium. It is located to the west of the crater Conon. To the west of this peak is the Rima Bradley rille. (See below.) The selenographic coordinates of this peak are . It has a maximum diameter of 30 km across the base, and rises to a height of about 4.2 km. It is named after the English astronomer James Bradley (1692–1762). Rima Bradley This is a graben-type rille located in the southeastern part of the Mare Imbrium, near the Montes Apenninus range. To the northwest is the prominent crater Archimedes. This rille follows a course to the southwest, starting at the Palus Putredinis, and cutting through a hummocky region. To the east of the northern end of this rille is Rima Hadley and the landing site of the Apollo 15 mission. This feature is centered at selenographic coordinates , and it has a maximum diameter of 161 km. The rille was named for the ne ...

Conon (crater)
Conon is a small but prominent lunar impact crater that lies in the eastern foothills of the Montes Apenninus mountain range. The crater is named for the Greek astronomer Conon of Samos ( 250 BCE). Just to the west of Conon is the long mountainous ridge Mons Bradley. The nearest craters possessing an eponym are Galen, about to the east, and Aratus, about the same distance to the northeast. Description The edge of Conon's rim is sharply defined and has not received significant erosion from later impacts. The inner wall is somewhat variable in width, and the interior floor forms an irregular oval shape. This irregularity may be due to the rough and uneven surface on which the crater was formed. The floor is rough, but lacks a central prominence of note. To the south, in the Sinus Fidei, is a sinuous rille that follows a course to the south-southeast. This rille is designated Rima Conon, and is named after this crater. Satellite craters By convention these features are ident ...

Archimedes (crater)
Archimedes is a large lunar impact crater on the eastern edges of the Mare Imbrium. Its diameter is 81 km. Description The diameter of Archimedes is the largest of any crater on the Mare Imbrium. The rim has a significant outer rampart brightened with ejecta and the upper portion of a terraced inner wall, but lacks the ray system associated with younger craters. A triangular promontory extends 30 kilometers from the southeast of the rim. The interior of the crater lacks a central peak, and is flooded with lava. It is devoid of significant raised features, although there are a few tiny meteor craters near the rim. Scattered wisps of bright ray material lie across the floor, most likely deposited by the impact that created Autolycus. Surroundings To the south of Archimedes extends the Montes Archimedes, a mountainous region. On the southeastern rim is the Palus Putredinis, a lava-flooded plain containing a system of rilles named the Rimae Archimedes, which extends ove ...

Jonathan's Space Report
''Jonathan's Space Report'' (JSR) is a newsletter about the Space Age, hosted at Jonathan's Space Page. It is written by Jonathan McDowell, a Center for Astrophysics Harvard & Smithsonian astrophysicist. It is updated as McDowell's schedule permits, but he tries to publish two issues each month. Originally the website was hosted on a Harvard University account, but was moved in late 2003 to a dedicated domain. Started in 1989, the newsletter reports on recent space launches, International Space Station activities and space craft developments. McDowell's report occasionally corrects NASA's official web sites, or provides additional data on classified launches that aren't available elsewhere. Associated projects on the JSR web site are: * A catalog of all known geosynchronous satellites and their current positions * A listing of satellite launch attempts * A cross-reference between catalog number and international designation of artificial satellites McDowell has long campaig ...

English Language
English is a West Germanic language of the Indo-European language family, with its earliest forms spoken by the inhabitants of early medieval England. It is named after the Angles, one of the ancient Germanic peoples that migrated to the island of Great Britain. Existing on a dialect continuum with Scots, and then closest related to the Low Saxon and Frisian languages, English is genealogically West Germanic. However, its vocabulary is also distinctively influenced by dialects of France (about 29% of Modern English words) and Latin (also about 29%), plus some grammar and a small amount of core vocabulary influenced by Old Norse (a North Germanic language). Speakers of English are called Anglophones. The earliest forms of English, collectively known as Old English, evolved from a group of West Germanic ( Ingvaeonic) dialects brought to Great Britain by Anglo-Saxon settlers in the 5th century and further mutated by Norse-speaking Viking settlers starting in ...

Scottish Gaelic Language
Scottish Gaelic ( gd, Gàidhlig ), also known as Scots Gaelic and Gaelic, is a Goidelic language (in the Celtic branch of the Indo-European language family) native to the Gaels of Scotland. As a Goidelic language, Scottish Gaelic, as well as both Irish and Manx, developed out of Old Irish. It became a distinct spoken language sometime in the 13th century in the Middle Irish period, although a common literary language was shared by the Gaels of both Ireland and Scotland until well into the 17th century. Most of modern Scotland was once Gaelic-speaking, as evidenced especially by Gaelic-language place names. In the 2011 census of Scotland, 57,375 people (1.1% of the Scottish population aged over 3 years old) reported being able to speak Gaelic, 1,275 fewer than in 2001. The highest percentages of Gaelic speakers were in the Outer Hebrides. Nevertheless, there is a language revival, and the number of speakers of the language under age 20 did not decrease between the 20 ...

Hebrew Language
Hebrew (; ; ) is a Northwest Semitic language of the Afroasiatic language family. Historically, it is one of the spoken languages of the Israelites and their longest-surviving descendants, the Jews and Samaritans. It was largely preserved throughout history as the main liturgical language of Judaism (since the Second Temple period) and Samaritanism. Hebrew is the only Canaanite language still spoken today, and serves as the only truly successful example of a dead language that has been revived. It is also one of only two Northwest Semitic languages still in use, with the other being Aramaic. The earliest examples of written Paleo-Hebrew date back to the 10th century BCE. Nearly all of the Hebrew Bible is written in Biblical Hebrew, with much of its present form in the dialect that scholars believe flourished around the 6th century BCE, during the time of the Babylonian captivity. For this reason, Hebrew has been referred to by Jews as ''Lashon Hakodesh'' (, ) since a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Selenographic Coordinate
The selenographic coordinate system is used to refer to locations on the surface of Earth's moon. Any position on the lunar surface can be referenced by specifying two numerical values, which are comparable to the latitude and longitude of Earth. The longitude gives the position east or west of the Moon's prime meridian, which is the line passing from the lunar north pole through the point on the lunar surface directly facing Earth to the lunar south pole. (See also Earth's prime meridian.) This can be thought of as the midpoint of the visible Moon as seen from the Earth. The latitude gives the position north or south of the lunar equator. Both of these coordinates are given in degrees. Astronomers defined the fundamental location in the selenographic coordinate system by the small, bowl-shaped satellite crater ' Mösting A'. The coordinates of this crater are defined as: : Later, the coordinate system has become more precisely defined due to the Lunar Laser Ranging ...

Apollo 15
Apollo 15 (July 26August 7, 1971) was the ninth crewed mission in the United States' Apollo program and the fourth to land on the Moon. It was the first J mission, with a longer stay on the Moon and a greater focus on science than earlier landings. Apollo 15 saw the first use of the Lunar Roving Vehicle. The mission began on July 26 and ended on August 7, with the lunar surface exploration taking place between July 30 and August 2. Commander David Scott and Lunar Module Pilot James Irwin landed near Hadley Rille and explored the local area using the rover, allowing them to travel further from the lunar module than had been possible on previous missions. They spent 18 hours on the Moon's surface on four extravehicular activities (EVA), and collected of surface material. At the same time, Command Module Pilot Alfred Worden orbited the Moon, operating the sensors in the scientific instrument module (SIM) bay of the service module. This suite of instruments co ...
